Nobles - Int vs Spirit

So due to recent changes I decided that it would probably be best if I did not use the nobles card on my alt but rather no my priest. My question is rather simple, what is more effective, int or spirit?

Int:
Crit
Mana
Larger gain from replenishment

Spirit:
Most likely more mp5(disregarding replenishment) than int
Spell power.

Re: Nobles - Int vs Spirit

Keep in mind that this will count your total int and spirit while raid buffed, so if you have more int than spirit while raid buffed that is the buff the card will give you. You don't want to get the wrong one and find out that raid buffed your int is still higher than your spirit.

I shall die here. Every inch of me shall perish. Every inch, but one. An inch. It is small and it is fragile and it is the only thing in the world worth having. We must never lose it or give it away. We must never let them take it from us.

This is not true in current content.
1 int yields up to 0.45-0.55 MP5 depending on spec and race. Blood elf Disc priests on top. Replenishment is about 1/3rd of that.
1 spi yields up to 0.35-0.45 FSR MP5 depending on spec and race, assuming 1293 intellect. Human Holypriests on top. It's a worse stat for manaregen, but you can triple the amount if you actually get out of the FSR, and although you don't do that often, it makes up for it. For spamfights, int is the king. For farming, nothing beats spirit. You pick a little of both and remain happy.

In 3.1 this balance change.
Shadowfiend becomes 20% better, and more reliable, so you can add 0.05 MP5 on the intellect scale.
OOFSR Spirit takes a 40% dip in efficiency. Meaning OOFSR spirit is now pretty crap, and the benefits from doing the OOFSR dance is getting very small. FSR spirit regen has no change.
This shifts the balance heavily in the favor of intellect.
But the new Holy Concentration theoretically adds 50% efficiency to spirit while active, so it will all totally depend on buff uptime.
Uptime equal to your crit rate seems likely, but this probably need some testing before we can say for sure.

I read that Spirit-world Glass and Je'Tze's bell were the best in slot items, wouldn't a combo of Nobles spirit card - darkmoon card - illusion have around the same results?
Or as stated before, if the int is better, then a combo of the int and the illusion deck.
